我有一些測驗，如果我沒有無頭地運行它，并且如果無頭模式在引導下運行我的測驗，那么一些測驗就會失敗，但無法定位元素。遇到這種情況怎么辦
視窗大小有多大也有關系嗎？目前我有以下內容，但我想如果他們通過希望這樣的視窗大小沒有無頭為什么有些會失敗無頭
@BeforeEach
public void setUp() {
WebDriverManager.chromedriver().setup();
driver = new ChromeDriver(new ChromeOptions()
.addArguments("start-maximized")
.addArguments("--disable-popup-blocking")
.addArguments("--headless"));
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
loginToEnvironment();
}
在無頭模式下，某些元素未定位
由 PageFactory.init 完成的元素初始化
public class BasePage {
public WebDriver driver;
protected Wait wait;
public BasePage(WebDriver driver) {
initializePage(driver);
this.wait = new Wait(driver);
}
final protected void initializePage(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(new AjaxElementLocatorFactory(driver, 20), this);
}
}
注冊測驗
@Test
public void shouldSignUpSuccessfully() {
signUpModal.signUp((SignUp) credentials)
.getCountryModalInstance()
.chooseCountry(((SignUp) credentials).getCountry())
.clickOnSaveButton();
assertTrue(homePage.getMyAccountName().getText().isEmpty());
}

對于這個 css 選擇器：
.user-name
請檢查dev tools（谷歌瀏覽器）我們是否有唯一的條目HTML DOM。
你應該檢查的css：
.user-name
檢查步驟：
Press F12 in Chrome- >去element節- >做一個CTRL F- >再貼上css看看，如果你需要的element是越來越強調與1/1匹配的節點。
如果我們有 1/1 匹配節點，請確保：
- 此 Web 元素不在 iframe 下。
- 此 Web 元素不在影子根目錄下。
- 您不應該在 selenium 啟動的新選項卡/視窗上。
如果它屬于上述任何類別，您將不得不處理該特定場景。

AjaxElementLocatorFactory
AjaxElementLocatorFactory是頁面工廠模式中的延遲加載概念，用于僅在任何操作中使用 WebElement 時識別它們，即可以在 AjaxElementLocatorFactory 的幫助下將 WebElement 的超時分配給 Object 頁面類。
因此，理想情況下，您需要將隱式等待洗掉為：
警告：不要混合隱式和顯式等待。這樣做可能會導致不可預測的等待時間。例如，設定 10 秒的隱式等待和 15 秒的顯式等待可能會導致在 20 秒后發生超時。
NoSuchElementException 表示未找到元素。
要定位元素，您可以使用以下任一定位器策略：
使用
css_selector：div.header-menu-item > div.header-menu-name span.user-name使用
xpath：//div[@class='header-menu-item']/div[@class='header-menu-item']//span[@class='user-name']
